In 2013, Pigeon Lake was included in a study conducted by the North Saskatchewan Watershed Alliance regarding stream nutrient data observations. There were 7 streams for pigeon lake studied over 54 days.

“…record lower values than expected for a nutrient-rich agricultural area. This might be attributed to the lower precipitation in 2013 (Figure 20) or perhaps the success of improved land management practices in the watershed. In addition, samples were only taken an average of every two weeks and may have missed peak flows from spring melt or summer storms.”
